关于构建springboot2.x出现报错镜像找不到springboot包的问题

报错原因

今天第一次学习springboot出现了报错，在2023.10.31构建springboot时springboot2只能够选择2.7.17版本，在JDK选择了与之匹配的1.8以后仍旧出现报错org.springframework.boot:spring-boot-starter-parent:pom:2.7.17.RELEASE was not found in http://maven.aliyun.com/nexus/content/groups/public/ during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of alimaven has elapsed or updates are forced。

解决方法

最后通过将pom.xml文件中的2.7.17.RELEASE改为2.7.17后问题解决

同时注意maven的镜像配置文件settings.xml，如果配置有问题会导致超时，爆一堆奇奇怪怪的错误。

settings.xml文件如下：
